'SPECIFICATION forming part of Letters Patent No. 433,709, dated August5, 1890.

Application filed April '7, 1890. Serial No. 346,858. (No model.)

To aZZ whom, it may concern:

Be it known that we, HEINRICH IVIESE and JOHN BRAAOK, of Milwaukee, inthe county of Milwaukee, and in the State of Wisconsin, have inventedcertain new and useful Improvements in Refrigerators; and we doherebydeclare that the following is a full, clear, and exact descriptionthereof.

Our invention relates to refrigerators; and it consists in certainpeculiarities of construction and combination of parts to be hereinafterdescribed with reference to the accompanying drawings, and subsequentlyclaimed.

In the drawings, Figure 1 represents a longitudinal section of arefrigerator constructed according to our invention; Fig. 2, atransverse-section of the same, and Fig. 3 adetail horizontal sectionillustrating an anti-friction bearing.

Referring by letter to the drawings, A represents the wall, B the top,and O the bottom, of a refrigerating-colnpartment, and arranged withinthis compartment is a cage D for holding ice. In the present form of ourinvention the ice-cage is provided with a bail E, and a central arm F ofthe bail extends up into a casing G on the top B of therefrigeratingcompartment. Secured to the bottom of the casing G is aplate I), and supported on this plate to surround the bail-arm E is aspiral spring II of considerable power, this spring being held in placeby means of a cross-head or washer c and nut (Z on the upper end of saidbail-arm. Secured to the inner sides of the compartm ent-walls A arebrackets II, and journaled in the latter are anti-friction rollers I,impinged against the bail E, and these rollers have flanges 6 adjacentto the edges of said bail to prevent the latter from swaying. The bail Eis provided with a finger J, that extends through a slot in the adjacentwall of the refrigeratiug-compartment to register with a scale-plate K,and depending from the bottom of the ice-cage D is a pipe f, that isloosely fitted in a nipple g on the cover of a water-receptacle L,connected to said wall. The water-receptacle is provided with a sieve h,to stop dirt that may come down with the drip from the ice-cage D, andbetween this sieve and another one 2' we arrange suitable filteringmaterial 7 to nent.

purposes. The ice-cage is normally supported by shoes on m, pivotallyconnected to a transverse iod P, the latter being passed throughlever-arms Q, R, pivotally arranged on bolts n, that pass through thewalls A of the refrigerating-compartment. The leverar1 n R is of greaterlength than the one Q, and is provided with a handle r, while at thesame time a spiral spring .9 on its pivot-bolt exerts sufficient forceto hold said armR in engagement with a catch S, secured to the adjacentcompartment-wall. If at any time it is desirable to ascertain the weightof the ice in the cage, the lever-arm R is disengaged from the catch andthrown to one side, as shown in dotted lines, Fig. 1. This operationbrings the shoes on m away from said cage and permits the latter todescend against the force of the spring H, the finger J on the bail Ebeing carried down along the scale-plate K to show the Weight of theice.

Arranged in the ice-cage is a vertical flue T, through which warm air inthe refrigerating-compartment ascends, and above the flue is a flangedplate U, that extends on opposite sides of said flue to divide anddeflect said air in two directions onto the ice to be cooled, afterwhich it descends into said compart ment, this circulation beingcontinuous. By means of the central flue and deflector the airis-distributed over a greatercooling-surface to thereby lessen theconsumption of ice.

For the purpose of ventilating the refrigerating-compartment a pipe V isfittedin the top thereof, as shown in Fig. 1.

By the construction just described we cheapen the manufacture of largerefrigerators, refrigerator-cars, &c., effect a saving in ice, andimprove the circulation of air, while at the same time we are enabled toaccurately determine the amount of ice on hand at any time.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is

1. A refrigerating-compartment, a bail arranged therein an d providedwith a verticallydisposed arm, a spiral spring arranged to surround thebail-arm, a cross-head carried by said bail-arm in opposition to thespring, and an ice-cage connected to the bail, substantially as setforth.

2. A refrigerating-compartment having a wall thereof provided with aslot, a bail arranged in the compartment and provided with a fingerextended through said slot, a vertically-disposed arm on the bail, aspiral spring arranged to surround the bail-arm, a

v cross-head carried by said bail-arm in opposition to the spring, andanice-cage connected to the bail, substantially as set forth.

3. A refrigerating-compartment, a yielding ice-cage arranged therein, atransverse rod provided with pivotal supporting-shoes arranged tonormally impinge against the icecage, and lever-arms pivoted to thewalls of said compartment and connected to said rod, Substantially asset forth.

4. A refrigerating-coinpartment, a springcontrolled ice-cage arrangedtherein, a transverse rod provided with pivotal supportingshoes arrangedto normally impinge against the ice-cage, lever-arms pivoted to thewalls of the compartment and connected to said rod, a spring arranged toexert its force against one of the lever-arms, and a catch for thislatter arm, substantially as set forth.

5. A refrigerating-compartment, a springcontrolled bail arrangedtherein, flanged antifriction rollers arranged to impinge against thebail, an ice-cage connected to said bail, and a pivotal support for saidcage, substantially as set forth.

In testimony that we claim the foregoing we have hereunto set our hands,at Milwaukee, in the county of Milwaukee and State of W'iscousin, in thepresence of two witnesses.
